Imibuzo Evame Ukubuzwa - Iwave Communications Co., Ltd.

1.Kungani sidinga inethiwekhi ezinikele?

1. Ngokwenhloso yenethiwekhi

Ngokwenhloso yenethiwekhi, inethiwekhi yenkampani yenethiwekhi inikeza izinsizakalo ze-inthanethi ezakhamuzini ukuze zenze inzuzo; ngakho-ke, opharetha banaka kuphela idatha ye-downlink kanye nokufakwa kwendawo ebalulekile. Ukuphepha komphakathi, ngakolunye uhlangothi, ngokuvamile kudinga inethiwekhi egcwele ezweni lonke enedatha eyengeziwe ye-uplink (isb, ukubhekwa kwevidiyo).

2. Kwezinye izimo

Kwezinye izimo, inethiwekhi yenkampani yenethiwekhi ingase ivalwe ngenjongo yokuphepha (isb, izigebengu zingase zilawule ibhomu zikude ngenethiwekhi yenkampani yenethiwekhi).

3. Emicimbini emikhulu

Emicimbini emikhulu, inethiwekhi yenkampani yenethiwekhi ingaminyana futhi ayikwazi ukuqinisekisa ikhwalithi Yesevisi(QoS).

2.Singakwazi kanjani ukulinganisa i-broadband kanye ne-narrowband investment?

1. I-Broadband yiyona mkhuba

I-Broadband iwumkhuba. Akusekho ukonga ukutshala imali ku-narrowband.

2. Kucatshangelwa umthamo wenethiwekhi kanye nezindleko zokuyilungisa

Uma kucatshangelwa umthamo wenethiwekhi kanye nezindleko zokuyilungisa, zonke izindleko ze-broadband zilingana ne-narrowband.

3. Phambukisa kancane kancane

Kancane kancane dlulisela isabelomali se-narrowband ekusetshenzisweni kwe-broadband.

4. Isu lokusatshalaliswa kwenethiwekhi

Isu lokusatshalaliswa kwenethiwekhi: Okokuqala, sebenzisa ukusabalala kwe-broadband okuqhubekayo ezindaweni ezinenzuzo ephezulu ngokuya ngokuminyana kwabantu, izinga lobugebengu, nezimfuneko zokuphepha.

3.Iyini inzuzo yohlelo lomyalo wesimo esiphuthumayo uma i-spectrum ezinikele ingatholakali?

1. Sebenzisana nomsebenzisi

Sebenzisana nomsebenzisi futhi usebenzise inethiwekhi yenkampani yenethiwekhi ngesevisi engeyona ye-MC(i-mission-critical).

2. Sebenzisa i-POC(PTT phezu kwamaselula)

Sebenzisa i-POC(PTT phezu kwamaselula) ekuxhumaneni okungeyona eye-MC.

3. Encane futhi elula

Itheminali encane futhi elula, enobufakazi obuthathu yesikhulu nomphathi. Izinhlelo zokusebenza zamaselula zamaphoyisa zisiza ibhizinisi elisemthethweni kanye nokugcinwa komthetho.

4. Hlanganisa i-POC

Hlanganisa i-POC kanye ne-narrowband trunking kanye nevidiyo engaguquki neselula ngohlelo lomyalo oluphathekayo lwezimo eziphuthumayo. Esikhungweni esihlanganisiwe sokuthumela, vula izinsiza eziningi ezifana nezwi, ividiyo, ne-GIS.

4.Ingabe lokho kungenzeka ukuthola ibanga lokudlulisa elingu-50km ngaphezulu?

Yebo. Kungenzeka

Yebo. Kungenzeka. Imodeli yethu ye-FIM-2450 isekela ibanga elingu-50km levidiyo nedatha ye-Bi-directional serial.

5.Uyini umehluko phakathi kwe-FDM-6600 ne-FD-6100?

Ithebula Likwenza Uqonde Umehluko Phakathi kwe-FDM-6600 kanye ne-FD-6100

6. Ingakanani i-hop count ephezulu yomsakazo we-IP MESH?

15 hops noma 31 hops

Amamodeli e-IWAVE IP MESH 1.0 angafinyelela kuma-hops angama-31 endaweni yaselabhorethri (inani elifanele, elingelona ithiyori), nokho-ke asikwazi ukulingisa isimo selabhorethri ngokusebenza okungokoqobo, ngakho-ke siphakamisa ukwakha inethiwekhi yokuxhumana enezinga eliphezulu lama-node angu-16 kanye nobuningi Ama-hops angu-15 asetshenziswa ngempela.

Amamodeli we-IWAVE IP MESH 2.0 angafinyelela ezindaweni ezingama-32, ama-hops aphezulu angama-31 ngokusebenza.

7.Ingabe idivayisi isekela ukudluliswa kwe-Unicast/Broadcast/Multicast?

Yebo, amadivaysi asekela ukudluliselwa kwe-Unicast/Broadcast/Multicast

8.Ingabe iyagxumagxuma?

Yebo, isekela i-frequency hopping

9.Uma kunjalo, inama-frequency hop ngomzuzwana?

100hops ngomzuzwana

10.Ingakwazi yini ukwaba izikhala zesikhathi esengeziwe ekudluliselweni kwevidiyo?

I-TS yesendlalelo esibonakalayo (indawo yesikhathi, njengesikhala sesikhathi somshayeli, i-uplink, ne-downlink yesikhathi yesevisi, indawo yesikhathi sokuvumelanisa, njll.) i-algorithm yokwaba isethwe kusengaphambili futhi ayikwazi ukulungiswa ngumsebenzisi.

11.Ingakwazi yini ukwaba izikhala zesikhathi ezengeziwe ekudluliselweni kwevidiyo?

I-algorithm yesendlalelo esibonakalayo isethwe kusengaphambili ku-TS (i-slot yesikhathi) i-algorithm yokwabiwa futhi ayikwazi ukulungiswa ngokuguqukayo ngumsebenzisi. Ngaphezu kwalokho, ukucutshungulwa okuhambisanayo phansi kwesendlalelo esibonakalayo (isabelo se-TS singesendlalelo esingaphansi kwesendlalelo esibonakalayo) akukhathaleli ukuthi idatha iyividiyo noma yezwi noma idatha evamile, ngakho-ke ngeke yabele i-TS eyengeziwe ngenxa nje yokuthi ukudluliswa kwevidiyo.

12.Uma idivayisi iqeda ukulandelana kokuqalisa, Yisiphi isikhathi esiphezulu sokujoyina sedivayisi kunethiwekhi ye-ADHOC?

Isikhathi sokujoyina singama-30ms.

13.Yiliphi izinga eliphezulu ledatha elingadluliswa ebangeni eliphakeme elishiwo?

Izinga ledatha yokudlulisela alincikile kuphela ebangeni lokudlulisela, kodwa futhi nasezicini ezihlukahlukene zemvelo ezingenazintambo, njenge-SNR.Ngokuhlangenwe nakho kwethu, I-200mw MESH module FD-6100 noma FD-61MN, umoya ukuya emhlabathini 11km, 7-8Mbps I-200mw Imojuli yenkanyezi ye-topology FDM-6600 noma i-FDM-66MN: Umoya ukuya phansi 22km: 1.5-2Mbps

14.Iyini ububanzi obulungisekayo bamandla we-FD-6100 ne-FDM-6600?

-40dbm~+25dBm

15.Indlela yokubuyisela Izilungiselelo zefekthri ze-FD-6100 ne-FDM-6600?

Ngemva kokuqala, donsa i-GPIO4 iphansi, cisha bese uqala kabusha i-FD-6100 noma i-FDM-6600. Ngemuva kokuthi i-GPIO4 iqhubeke nokudonselwa phansi imizuzwana eyi-10, bese ukhulula i-GPIO4. Ngalesi sikhathi, ngemva kokuqalisa, izobuyiselwa efekthri. Futhi i-IP ezenzakalelayo ithi 192.168.1.12

16.Yini isivinini esikhulu sokunyakaza esingasekelwa yi-FDM-6680, FDM-6600 ne-FD-6100?

I-FDM-6680: 300km/h FDM-6600: 200km/h FD-6100: 80km/h

17.Ingabe i-FDM-6600 ne-FD-6100 ziyayisekela i-MIMO? Uma kungenjalo, ungachaza ukuthi kungani imikhiqizo ine-2 RF inputs? Ingabe le Tx/Rx imigqa ehlukene?

Basekela i-1T2R. Phakathi kwezixhumanisi ezimbili ze-RF, eyodwa yi-AUX. interface, engasetshenziselwa ukwehlukahlukana kokwamukela ukuze kuthuthukiswe ukwamukela okungenantambo. ukuzwela (kukhona umehluko we-2dbi~3dbi phakathi kwe-antenna exhunyiwe nengaxhumekile enembobo ye-AUX).

18.Ingabe i-FDM-6680 iyayisekela i-MIMO?

Yebo. Isekela i-2X2 MIMO.

19.Yiliphi ikhono lokudlulisela phambili eliphezulu? Lishintsha kanjani izinga ledatha ngokuya ngesibalo sokudlulisela.

Isincomo sethu siwumkhawulo we-15 relay, kodwa inani langempela lokudlulisela kumele lisekelwe endaweni yangempela yokuxhumana phakathi nokufakwa kwesicelo. Ngokombono, ukudluliselwa ngakunye okwengeziwe kuzonciphisa ukuphuma kwedatha cishe ngo-1/3 (kodwa futhi kungaphansi kwekhwalithi yesiginali nokuphazamiseka kwemvelo nezinye izici).

20.Yiliphi izinga eliphezulu ledatha elingadluliswa ebangeni eliphakeme elishiwo? Ingakanani inani elincane le-SNR kulesi simo?

Ake sithathe isibonelo ukuze sichaze lo mbuzo: Uma i-UAV indizela ubude obungamamitha ayi-100 ngemojula ye-FD-6100 noma i-FD-61MN ebhodini (ibanga eliphezulu le-FD-6100 ne-FD-61MN lilinganiselwa ku-11km), uthi Iyunithi yomamukeli igxilile ngamamitha angu-1.5 ngaphezu komhlabathi.

Uma usebenzisa i-2dbi antenna kukho kokubili. I-Tx ne-Rx Uma ibanga ukusuka ku-UAV ukuya esikhungweni sokulawula umhlaba kungu-11km, i-SNR icishe ibe +2, kanti izinga lokudlulisa idatha ngu-2Mbps.

Uma usebenzisa i-2dbi Tx antenna, i-5dbi Rx antenna. Uma ibanga ukusuka ku-UAV ukuya esikhungweni sokulawula umhlaba kungu-11km, i-SNR icishe ibe +6 noma +7, futhi izinga lokudlulisa idatha lingu-7-8Mbps.

21Ingabe iyagxumagxuma?

I-FHHS frequency hopping inqunywa i-algorithm eyakhelwe ngaphakathi. I-algorithm izokhetha iphoyinti elifanele lokuvama ngokususelwe kusimo samanje sokuphazamiseka bese isebenzisa i-FHSS ukuze weqe kulelo phuzu lokuvama elilungile.
